With more man-hours being spent on programming work, differences in worker-created measurement programs, and inefficient programs being created due to proficiency issues, the industry has moved from 2-D drawings to 3-D annotated models. A number of factors—the increased emphasis on quality control, the growing diversity of parts and components being measured, the development of more complex global supply chains and reduced product lifecycles—have led to a considerable demand for automatic measurement programming in recent years.
